A search warrant authorized by a local judge is shedding more light on the tragic May 9 shootout that killed one Killeen police officer and injured another.

The search warrant, issued May 8, authorized Killeen police to search the apartment and two vehicles of 49-year-old Marvin Louis Guy. The warrant, created by the Bell County Organized Crime Unit, stated that investigators believed they would find cocaine, money and possibly weapons.

Killeen municipal judge Mark Kimball signed the warrant, and also authorized police to conduct a "no knock" entry.

So-called "no knock" authorization exempts law enforcement from identifying themselves and announce their purpose before using force to enter a dwelling with a search warrant.

U.S. Supreme Court rulings have established some exceptions to the "knock and announce rule", such as risk of injury to the officer executing the search warrant, if there is a risk of the occupants destroying evidence.

A subsequent search warrant issued after the shooting did not specify whether or not the officers involved in the May 9 incident announced themselves before Guy opened fire on them.

This article leaves too much to the imagination. If you're not in law enforcement you have no idea of the thought process behind a "no-knock" warrant. Why would you want to knock if it's a high risk warrant? I would assume that you would want to catch the person off-guard. Nonetheless, a great man lost his life because of a scumbag with drugs. This community and a family is at a loss. So if you don't have anything good to say, have some respect, and keep your thoughts to yourself.
